    La105 Problems

    I'm new here (but not to engines), so excuse me if I am missing something.

    I have a La105 tractor, and I've been having some problems with it.

    I had to replace the ignition setup (key and all) since mine broke and some pieces were lost. (Long story, don't ask.) I bought this from ebay:

    http://cgi.ebay.com/ws/eBayISAPI.dll...#ht_1045wt_907

    I hooked it up, made sure the battery had a full charge, made sure the brake was on, the blades were off, everything. I put the key in the ignition and turn it, and get nothing. No cranking, no noise. Also, the "Service reminder" hour meter isn't going on.

    My lawn eventually got REALLY long, and I wasn't going to mow my 4 acre lawn with a pushmower.

    I found out that if I put the key in the ignition and turn it, I can then start the engine by using a piece of heavy gauge wire and connecting the two posts on the starter solenoid.

    I can run it like this for awhile, then the engine quits. It can, however be restarted.

    If it helps, the Reverse Implement Option button does not work, at all. But if I shift into reverse while mowing the engine will cut off.

    If anyone has any ideas what my problem could be, please tell me.


    Thanks,

    Nate.

    I would take a look at your PTO and seat switches. do you have a multimeter or test light?

    No, I do not. Where could I get one?

    Also, the "Hour Counter" (for lack of a better name) doesn't turn on unless the engine is running. (if it helps).

    Also, If I get off the mower without it in park it will turn off, so the seat switch is working. Is there more than one?

    And where could I find my pto switches?

    Thanks,

    -nate

    Test equipment is available almost anywhere. Wal-Mart, Autozone would be cheapest. NAPA would probably have better quality. A test light is easier to use. The yellow wire 401 should feed power to the hour meter (with the keyswitch in run). I assume your PTO in not electrically activated, so your switch will be under the cowl by the back of the lever. Check for power on 943 white at PTO switch (also with key on).

    I'll give those wires a check and pick up a test light on my way home from work today.

    I was too hasty when I was refilling my oil and I got my oil a little above the line on the oil checker thing. I'm a computer guy, worst motor/mechanic ever. I know nothing.

    Anyway, it won't start at all now. It'll spin, no fire. Do I need to drain some oil? If so, what do I do after that? Should I let it run a few spins with the spark plug out to clean anything? Is there anything I can manually clean or check? My bro-in-law who is a farmer says there's a kill switch that would have enabled if I put too much oil in it and I'd need to manually turn that off. Where's that at? LA105

    Thanks

    PS - everyone tells me LA105 is not real John Deere. Is this true?

    Drained oil to correct placement, let the sparkplug slot blow until it was blowing fuel only (so far as I can tell), tried two different spark plugs, no fire, no ignite.

    plz help. i'm about to go mower shopping i guess

    You've probably already thought of this, but are you sure that it is getting fuel? Maybe it isn't a fowled plug, but a fuel issue.

    Yeah I mean if I start the mower without the spark plug I can see crystal golden fuel squirting like crazy. It's like it's not getting/accepting/creating a spark to ignite the rest of the process.

    I'm seriously ready push this thing out into the street. Even if it's my fault, I feel like I've done -everything- other than torch it.
